Maximum Spans and Fastening Pattern for Corrugate Wall Cladding
The maximum span for pan fastened wall cladding is generally governed by temporary deflection under load, rather than permanent deflection around the fastener.
Maximum Span for Wall Cladding: 5 Fasteners per Sheet (every second trough)
| *Serviceability load governs | |||
| The deflection criteria used in this table is span/120 + P/30, where P = the space between fasteners. Higher deflection limits may be acceptable in certain circumstances. | |||
| Wind Zone | Load (kPa)* | Maximum Spans | |
|---|---|---|---|
| 0.40 mm | 0.55 mm | ||
| Medium | 0.93 | 1.80 | 2.10 |
| High | 1.32 | 1.50 | 1.80 |
| Very High | 1.72 | 1.40 | 1.60 |
| Extra High | 2.09 | 1.20 | 1.50 |
